Our results suggest that C-terminal-to-N-terminal contacts in alphaS are not strongly protective against aggregation, and that the dominant mechanism by which PD-linked mutations facilitate alphaS aggregation may be altering the physicochemical properties of the protein such as net charge (E46K) and secondary structure propensity (A30P and A53T).

Among familial forms of PD, a small fraction is caused by missense (A53T, A30P and E46K) and copy number mutations in SNCA which encodes alpha-synuclein, a primary protein constituent of Lewy bodies, the pathognomonic protein aggregates found in neurons in PD.
